How can I find a .I file or an expanded source code file of C program code blocks?

It’s funny how almost any term in programming may be used to name something, like Code::Blocks. If your question would be about that, I think you would have written so. Code block is very much a natural language term about any block of code, a few lines doing something. In a special case it can be used to refer to a certain extent of code between bracket keywords, eg all lines between a whole if..endif statement or just the lines of the if ..else branch vs. the lines of the else..endif branch. It could be any lines not delimited with such keywords of the typical curly brackets used in C/C++/C# and some other languages. But mostly it is not a strict term having just one sepcific meaning. In forums or here at Quora a code block might also simply refer to a code box like the following: print(“hello world”) GitHub explicitly calls such boxes or areas code block, blocks of syntax highlighting in a monospaced font with coloring and other characteristics of a language. So in this context it is a layout element term of forums, wikis, blogs, web pages publishing code samples in general, see: read less
